Additive manufacturing of multi-composition glass optics

Techniques for three-dimensional (3d) printing of glass have opened the door to novel glass structures with both unconventional structures and tailored composition. The state-of-the art in glass 3d printing and associated challenges will be presented. Emphasis will be placed on the direct ink writing approach, which can be used to produce multi-composition optics such as GRIN lenses. The discussion will cover formulation science, mass transport in multi-material systems, as well as strategies for formation of glass and multi-material optics.
